I was going through one of those "Post your desktop pics" thread on another forum when I noticed something was wrong. As you know many of the desktop pics people post are very wide and require side scrolling. Well as I was side scrolling I noticed the image would jag on the edges and also the webpage. I pulled out my black Macbook to see if the same would happen but it did not. I guess I have to take my 13" MBP to the apple store tomorrow.
